BOX-ASSEMBLING MACHINE.

Specification of Letters Patent.

Patented J une 1, 1915.

- Application filed July 2, 1914. Serial No. 848,530.

- citizen of the UnitedStates, residing at Chil0. 'bodies by meansoperating at high speed,

cago, in the county of Cook and State of Illinois, have invented certainnew and usefulImprovement-s in Box-Assembling Machines, of which thefollowing is a specification.

The salient feature of the present invention is the assembling ofboxcovers on boxthereby performing such function with rapidity anddespatch.

The improved machine incorporating this invention, although not limitedto such use,

is especially applicable for placing covers telescopically on necked orcollared pasteboard boxes of rectangular shape, such for example, as areordinarily used for. cigarettes.

In the preferred embodiment of the invention, the boxes and covers arefed in series toward one another in opposite directions by suitablemeans, each cover being brought into register with one of the boxes andapplied thereto by first fitting one end of the cover over the neck, butnot pressing the same home on the box, then turning the cover down overthe box so that its sides fit over those of the neck, and then spreadingslightly or guiding the opposite end of the cover, and while in thiscondition, closing it over the corresponding end of the neck,subsequently pressing the cover full down on the box so as to completelyinclose the neck and bear against the edges of the box-walls proper.That is to say, the manner of applying the cover to the box by thismechanism is slightly analogous to the method of fitting a' low shoe onthe foot by means of a shoe-horn.

One particular feature of advantage in a machine of this characterresides in the fact that the covers are applied to the boxes during theuninterrupted travel of both elements, whereby the assembling is broughtabout at an economical high speed of operation of the machine.

A preferred embodiment of this invention in a machine is illustrated inthe accompany ing drawings forming a part of this specification, adetailed description of the structural elements of such machine andtheir functions being given below.

In these drawings: Figure 1 is a fragmentary elevation of the machine;Fig. 2 is an end elevation of the same; Fig. 3 is a'substantiallycentral vertical cross-section on an enlarged scale; Fig. 4 is afragmentary elevation of the lower portion of the mechanism on anenlarged scale; Fig. 5 is a crosssection on line 55 of Fig. 4; Fig. 6 isa cross-section on line 66 of Fig. 4; Fig. 7

is an enlarged view of the portion of the mechanism where thebox-elements are brought together for assembling; Fig. 8 is a similarsection illustrating the partial closmg of the cover on the box; Fig. 9illustrates the positions of the box elements prior to that which theyassume illustrated in Fig. 8. Fig. 10 the next step in the closingoperation after that shown in Fig. 8; Fig. 11 shows the box completelyclosed; Fig. 12 illustrates in perspective a series of curved fingerswhich rock the box-cover in the closmg operation, and Fig. 13 is afragmentary detail illustrating the means for bringing the box-elementssidewise into exact register.

This machine comprises a hollow-base or standard 20 on which the greaterportion of the mechanism is mounted. Projecting forwardly from the upperpart of this standard and rotatable in suitable bearings therein are twoshafts 21 and 22 equipped with driving-gears 23 and 24 respectively,shaft 21, (by means of mechanism not necessary to describe), beingadjustable to a slight degree toward and from the shaft 22. Carried byand grouped around these two shafts are the principal parts of themachine performing the box-closing operation, that is, the assembling ofthe box elements. The teeth of gear 24 are in mesh with an intermediategear 25 mounted on a shaft 26 revoluble in hearings in the standard,(Fig. 3). Gear 27 611 shaft 28, (Figs. 1 and 3), rotatable in bearingsof the standard, is in mesh with the teeth of gears 23 and 25 and alsoin mesh with the drivingpinion 29 on shaft 30 which at the rearof themachine, as shownin Fig. 2, is supplied with a drive-pulley 31 which maybe belted up to any suitable source of power, such as an electric-motor.Obviouslv then, the rotation of pulley 31 and shaft 30 is transmittedthrough the train of gears so as to rotate the shafts 21 and 22 inopposite directions, the former clockwise, and the latter'counter-clockwise. Shaft 21 has fastened thereto and revolubletherewith, a.

pair of spaced disks 32 and 33, (Figs. 2 and 4 3), each having aninwardly-extended flange or circular rib 34 and 35 respectively, to theinner faces of which are fastened the pair of disks 36 circular ingeneral conformation, but also provided with a plurality. of fiat faces37, those of the two disks being in angular register. Centrally betweenthese disks 36,-and which may be held in position by circular-flanges 38on the disks, is a sprocket-wheel 39 in cotiperative relation with asprocket-chain 40 pro vided at intervals with outstanding lugs orfingers 41, 41, adapted when they pass around the shaft 21 to be inregister with the flat faces 37, as shown for example in Fig. 8. Thissprocket-chain, some distance away from the standard 20, passes aroundanother sprocket-wheel, (not illustrated), as is customary. Chain 40passes between a pair of supporting-strips or bars 42, 42, (Fig. 2), onwhich the necked, rectangular cigarette-boxes are adapted to slide, being ushed along by the upwardly-projecting lhgs 41 until they reach thecompositewheel, made up with the various partsdcscribed, on the shaft21, and then each ox rests upon two of the surfaces 37, its rearedgebearing against its coiiperati ng stop 41 on the chain. This 0 erationis perhaps best illustrated in Fig.

For each pair of the fiat surfaces 37 I pivot on each of the disks 32-'and 33 at 43 the arms 44 and 45 (Figs. 3 and 7 these arms at one endbeing cross-connected together b the: shaft 46 accommodated in curved sots 47 of the two disks. These arms 44 and 45 are pivoted on the innerfaces of the disks 32, and 33 and extend through'suitable openings48,(Fig. 3), in

. back against the lug 41 on the chain, that is,.they prevent the boxfrom slidin forwardly or downwardly and also limit the extent ofapplication of the cover to the box until they are withdrawn. In orderthat they may perform this function, each pair of these arms 44 and 45is supplied with a coil-contractile-spring 52, (Fig. 1), fastened to thearm 44 and also to the disk, the contractile action of the springswinging thearms on their pivots 43 and holding them in the positionillustrated in Fig. 7.

The disk 32 opposite each of the pair of flat surfac s 37 is equippedwith a boss 53 (Fig. 13) siidingly receiving a pin 54 con- I nected to aleaf-spring 55 tendin to retract -application of the box-cover.

order to position each of the boxes sidewise just prior to its receptionof its cover, I mount on the machineframe an outwardly projectingstud-shaft 56, the outerend of which has a plate 57 fastened thereto, towhich is secured a bent-arm 58, (Figs. 1 and 13). As the boxes and pins54 come into register with the end-portion of the bar 58, the latterpushes the pins in, as shown in Fig. 13, and forces the boxes overagainst the disk 33, in this way'properly positioning and gaging themfor the reception of their respective covers.

In order to actuate the pairs of arms 44 and 45 I mount on themachineframe a bent-support 59 carrying on its inner-face a cam-block 60with which rollers 61 on the protruding-ends of the shafts 46 areadapted to coiiperate. That is to say, as the rollers ride on thesurface of this cam, as

illustrated in Fig. -1, the arms 44 and 45 will swing on their pivots sothat their boxthe corresponding lug 41 of the chain, permitting the freeand ready transfer of the boxes from their stationary supporting-bars42, 42, to the flat-surfaced rotary-disks 36. As soon, however, astherollers pass off of the end ofthe cam-block 60 the arms 44 and 45swing on their pivots under the action of their springs 52 so that'theteeth 49 engage the box-neck or collar just above the edge of thebox-wall and hold the box against the traveling-stop 41. After the boxhas received its cover, as explained hereinafter, it is necessary to'retract the pro truding-ends of the arms 44, 45, and their teeth orfingers 49 to permit the discharge of the box, and this is accomplishedreadily and easily by means of a stationar -bar 62 having aninwardly-bent end 63, Fig. 3). When one of the rollers 61 strikes thestop 63 during the rotation of the shaft21 and the parts carried.thereby the roller willbe temporarily held against movement andtheturning of the disk 32'Will cause the arms 44 and 45 to swing on theirpivots out of the way of the box, the shaft 46 traveling in the slots47. As soon, however, as the roller leaves the stop 63 from which itpasses after a momentary detention the arms 44 and 45 swing back tonormal position under the influence of their springs, as. will bereadily understood.

The mechanism mounted: on and rotatable With the shaft 22 is much likethat on the companion shaft 21, the shaft 22 and its parts beingprovided for the conveying and This structure comprises the inner andouter disks 65 and 66 respectively, the flat-surfaced disks 67-, theforward-end ofeach flat surface of which is provided with a stop orgage-pin 68, and the central sprocket-wheel 69, the parts being allclamped or fastened together in any suitable or approved manner. Asprocket-chain 70 with spaced-lugs 71 cooperates with the wheel 69 andanother sprocket-wheel (not illustrated), spaced away from the shaft 22some distance. As in the previous instance, the lugs 71 convey thebox-covers on suitable stationary-supports until they arrive ,andbecomepositioned on the flat surfaces of the disks 67 and as they rotatedownwardly they slide into contact with the stop-pins 68, as illustratedin dotted lines in Fig. 8. As is illustrated in the various figures, andin perspective in Fig. 12, the appliance is equipped with a member 72suitably supported in osition so that its four upstanding-fingers 3 withbowed or bent-ends 74 are spaced between the disks 65 and 66, the disks67, and the sprocket-wheel 69, so that their bentends are in theposition illustrated in Fig. 8. The companion box-conveying structure isprovided with a stripping-device 75 suitably supported in any approvedmanner and having a pair of upwardly-extended curved tongues 76 spacedbetween sprocket-chain 40 and the adjacent box-element supportingdisks36 so that in their downward travel the boxes are compelled to leave therotary mechanism and travel downwardly between the member 75 and thefingers 73 of the oppositevmember 72, (see Fig. 11). 7

In order to make certain that the boxcovers will travel forwardlyagainst the gage or stop-pins 68 and away from the chain-lugs 71, Iprovide an air-blast to assist gravity in such movement of the boxes.This mechanism comprises an oscillatory air-pump 77, (Fig. 2), mountedon a bracket 78 secured to the rear of the main-frame, the piston of thepump being connected by a rod 9 with a crank-pin 80 on a disk 81 securedto the oute end of shaft 30 beyond a hearing 82 b zed to the main-frameand assisting in the support of the shaft. Also mounted on the top ofthe machine and adjustable by means of a bolt 83 a bracket 84 isprovided carrying a curved-plate 85 extending over the path of travel ofthe box-covers. This plate is equipped with a nozzle 86 connected bysuitable piping 87 with the airpump 77. The operation of this part ofthe mechanism is as follows: When the boxcover 88 reaches the positionsubstantially as indicated in Fig. 8, if it fails to slide forwardlyagainst its stop-pins 68 under the action of gravity it will besubjected to a blast of air, which, playing upon the interior of thecover, pushes it forwardly into position, the operation of the air-pumpbeing so timed as to deliver these air-blasts in proper timed relationto the travel and position of the box-covers.

On the stud-shaft 56 a collar 89 is loosely mounted and has attachedthereto by means of a s rew 90. one end of a coil-contractile spring 91,the other end being fastened to any suitable stationary part of themachine, as for instance, the bracket 84 or plate 85. Collar 89 carriesa depending, thin, flexible, metal-spring 92 with a hook-end 93 adaptedas explained hereinafter, to assist in the application of the covers tothe boxes, fitting between the boxes and covers and expanding orstretching the latter slightly, or guiding them to facilitate theirapplication.

The stationary-plate 57 described above and mounted on the shaft 56, hasfastened thereto a depending bar 94 corresponding in construction andfunction to the bar 58 and cooperating with the spring-pressed guidingor gaging-pins 95, in construction and purpose like the pins 54 of thecompanion mechanism.

The assembled boxes and covers upon leaving the conveying mechanism, ashas been explained, pass down between the parts 75' and 73 and areprevented from. lateral displacement by a pair of oppositely-disposedupstanding'bars 96 and 97 (Fig. 3), and if desired, the member 75instead of being rigidly supported may be rockingly mounted on a shaft98, (Fig. 4), and equ pped with an adjusting-screw 99 bearing against abifurcated arm 100 hung on the shaft 98 and carrying at one end a roller101 cooperating with a cam 102 on. a rotatingshaft 103.

The discharge-mechanism for the assembled box-bodies and covers forms nopart of the present invention and needs no description except thestatement that the horizontal passage has a retarding-brush 104:, areciprocatory delivery-plate 105, and a cotiperating plunger 106. Thismechanism is described and claimed, in my co-pending application, SerialNo. 779,486.

Operation: The operation of this im proved mechanism is substantially asfollows: The cigarette or other box-bodies 50 are advanced to theassembling-portion. of the mechanism by means of the sprocketchain 40and its spaced abutments or shoulders 41. W'hen these boxes reach thecentral portion of the machine, each bears on a pair of fiat surfaces 37of the rotary member with which the sprocket-chain co-acts. When eachbox-body reaches the upper-portion of the rotary-mechanism mounted onshaft 21, its corresponding positioning and cover-limiting arms 44, 45,are retracted against the action of their spring 52', as illustrated inFig. 1, by the engagement of their roller 61 with the stationary-cam 60.As the box-body advances, however, and the shaft 21 turns, the roller 61rides 01f of the end of the cam 60, permitting the arms 44, 45, torespond to the contractile action of the spring 52 and turn on theirpivots 43 so as to engage the box-neck just above the edge of thebox-rim, as illustrated, for example in Fig. 7 thereby holding the boxin proper position against its abutment 41, preventing it from fallingforwardly as it passes downwardly around the axis of shaft 21. Justbefore it reaches the position for the application of its cover, the arm58, by engagement 'with the corresponding springpin 54, positivelypushes the box over against the guide 33 into proper position forregistration with the companion cover. During such advance of eachnecked or collared box-body, its companion cover is be ing advancedtoward the body by the sprocket-chain and the corresponding abutment orlug 7]. carried thereby, it being understood that the bodies and coversare both advanced continuously in series so hat the machine may operatewith a high degree of elliciency and at relatively high speed. As thebox cover begins to turn down as it travels around the .haft 22, iteither talls forwardly by gravity into contact with the stop orgage-pins 68, or else it is pushed into contact with such pins by theblast of air which is periodically emitted from the nozzle 86. As itcontinues its i'orward downward travel, its springpressed pin it ispushed inwardly by the stationary-bar 34 so that the cover is broughtsidcwise into proper register with the companion box.

As each box and its cover approach each othri and travel downwardlyaround their respective shafts 2i and they reach the positions indicatedin Fig. 7, that is, the lower end of the cruel is brought into registerwith and fitted over one end of the neck, being prevented from being completely applied at this end by the presence of the limiting lingers orlu s alil, which de termine the extent of the telescopic application oihe rover to the box. It should be noted that the spring-linger 92projects inside ol' the b x, as illustrated in this figure.

As the partially assembled box and cover proceed dounwardlv, the fingersor lugs lit remain in the same position, because they are carried by therotary men'ibcr mounted on the shall 21. and as the parts movedownwardly, the cover 8 strikes the convex ends Tlot' the bar Ti whichcause it to lflt'li or turn over on to the box-neck in substaut'ia lvthe manner illustrated in Figs. 7 and and. since one end of the coverhad been previ ush applied over one end of the neck, no dillicuity isexperienced in applying the r ver owr the sides of the neck. as it isturned down as described. \l'hen the roller (Bl strikes the stationaryabutment (iii, the arms, H are rapidly rotated on their i'ulcrums l3,removing the fingers or lugs 49 from between the cover and box, theparts being illustrated in Fig. 8 in the positions they assume justprevious to such retraction of the fingers and in Fig. 10, the positionwhich they take just after such retraction. This, of course, permits thecomplete telescoping of one end of the cover over the advance end of thebox, and during 70 the further downward movement of the parts the hook93 of the resilient arm 92 engages the end-wall of the cover and extendsit slightly to facilitate its application over the end-Wall of the neck,as illustrated in Fig. 10.

As the assembled box and cover pass downwardly between the guides orarms 73 and 75, and 96 and 97, the cover is'pushed fully home on the boxso that as the latter emerges from the lower end of this pasthebox-elcments are completely'assembled. If necessary or desirable, thebar 75 may be given a slight rocking movement by means of the cam 102acting on the roller 101, as will be readily understood, but this isfrequently not necessary.

As the shaft 21 and the parts carried thereby continue their rotation,the roller 61 passes off of the abutment 63, permitting the arms it 45,to respond to the action of their spring 52, and as the roller 61travels upwardly it again engages the fixed-cam ti rocking the arms 44,45, for the reception between them and one of the abutments 41 on thechain 40, of another box 50.

It might be noted that the spring 91 acting on the arm 92 aids inretracting the arm from engagement with the end-wall of the cover assoon as the hook 93 has extended the cover sufficiently to permit itsready application over the end-wall of the neck.

it should be clear from this description and illustration that thebox-bodies are fed forwardly in a continuous series and that the boxcovers are advanced toward them in the opposite direction in. acontinuous series and in such timed relation that the covers willregister with the individual boxes and be applied thereto over the cololars or necks in the manner indicated and that the assembled boxes andcovers will he delivered from the lower. part of the machine in acontinuous series and discharged from the machine by mechanismunnecessary here to detail.-

Of course, many minor mechanical changes may be made in the mechanismshown and described in detail herein Without departing from thesubstance of this invention and without sacrificing any of its materialbenefits.
